Apre-paid cell phone company charges $12.95 as a monthly access fee and .16 cents per minute of calling time.
express the monthly cost c in terms of minutes of call time.
what will monthly cost be if you make 415 minutes of calls this month?

C = $20.15

Explanation:

Let's write down what is given first. There is a customary and non-changing $12.95 fee per month regardless of the actual cost to call. There are o.16 cents PER minute of calling, so 1 minute of calling = 0.16 cents. 415 minutes of calls are made in this month. C is the total cost.

We can write a function expression wih the given so when we input the value of the minutes, we get the answer.

x = no. of minutes

C =

f(x) = 0.16x + 12.95

We already know what x is here.

x = 415

Input the value of x into the function.

= 0.16(415)+12.95

= 7.2 + 12.95

= 20.15

C = $20.15

Hope this helped :)!
